Breton Woods was already de facto pulled out of by 1947, because of, ahem, massive government debt in Europe that the US had to subsidize. Attempts to say otherwise are not historically accurate, but I can't imagine historical accuracy is pertinent to this type of fantasy. Offset payments don't really work when denominated in a single government's currency, because you know, the locals sort of like to use their own currency for shit at the hardware store and restaurants and whatnot. And unless or until a country can produce all of its own goods without trade, or we become a One World Government, we're pretty much stuck with trade imbalances, and at least one country involved in the trade is going to use another government's money in those situations (although it's both countries a lot of the time). There are times when I think I couldn't respect Bernie Sanders any less than I already do, but then I always find a way to go lower.

Edit to say that those bunkers made my day. I can't believe I've never some across that before.
